I Saw European premiere of this movie and saw no review, so I will try to write one. I didn't see the parent story (which one is already on my list of anime that I plan to watch), so maybe that's the reason why some things were little unclear but overall even me as a newcomer was able to get "into action". Story was pretty typical of this kind of anime but characters are pretty good and the movie itself had many interesting and funny moments. The movie went pretty fastly forward so I have many "questions" that will be hopefully answered in season 1 and coming season 2 of anime. I enjoyed the movie, maybe it doesn't bring anything new but anyways I believe it's worth to see it.
